Cold Bonding of Iron Ore Concentrate Pellets
Iron ore concentrate pellets are traditionally hardened at high temperatures in horizontal grates and grate-kiln furnaces. However, heat induration requires tremendous quantities of energy to produce high-quality pellets, and is consequently expensive. Cold bonding is a low-temperature alternative to heat induration.

A review of binders in iron ore pelletization | Request PDF
For successful blast furnace processing, the barest minimum iron ore content required is around 58wt% (Meyer, 1980). Often, pellets are held to much more stringent requirements, of 62wt% iron or ...
Iron Ore Pelletization: Part II. Inorganic Binders
Iron Ore Pelletization: Part II. Inorganic Binders. ABSTRACT The addition of pellet binders often represents a compromise between the pellet grade and quality measures as strength, reducibility, and dustiness. Each inorganic compound present within the pellet plays a specific role in each aspect of creating a high-quality pellet.
Iron ore pelletization
Direct reduction (DR) of iron ore with hydrogen is a potential route for near-zero CO 2 steelmaking, but vertical shaft DR reactors require that iron ore fines must first be pelletized.
